IMHO that's exactly wrong. The problem is far too much will, and not enough competence. This is the second forum where I've seen a "not enough will" comment, despite it making no sense when you look at the history of the excessive amounts of capital thrown unproductively at the task.
Nuclear has some amazing lobbying going for it, amazing backers that will throw away billions of tens of billions of dollars into black pits of construction hell, despite knowing the rate of so many construction projects before it. And they take this massive risk without the possibility of VC like upsides; the financial upside of nuclear is minesxule compared to the massive risk of building. It makes no financial sense to any rational person.
No, the problem is certainly not a lack of will. The problem is that those pushing nuclear don't know how to build it. They like the idea, but don't have the skills and can't hire people with the skills. Nuclear construction is all a game of raking in some contracting cash and making sure that when the inevitable lawsuit comes due to failed construction, your side doesn't lose.
